Bonuses feel lower after taxes because the IRS considers them "supplemental income," requiring employers to withhold taxes at a higher flat rate—typically 22% federally—than regular paychecks. This immediate, heavy withholding, combined with FICA (Social Security/Medicare) and state taxes, reduces the net amount significantly.
Bonuses are considered wages and are taxed the same way as other wages on your tax return. However, the IRS doesn't consider them regular wages. Instead, your bonus counts as supplemental wages and can be subject to different federal withholding rules than your regular wages when your get paid your bonus.
You can't entirely avoid taxes on a bonus, but you can significantly lower the amount by contributing to tax-advantaged accounts (401(k), IRA, HSA), deferring the bonus to a year you expect to be in a lower tax bracket, or making charitable donations, thereby reducing your taxable income or increasing deductions at tax time.
Bonuses are considered “supplemental income,” which simply means money you earn over and above your regular paycheque. In Canada, this supplemental income is subject to income tax, just like your regular salary. In other words, your regular salary and your bonus are subject to the exact same amount and type of tax.
For a $70,000 income in Canada (using 2025 rates), you'll pay roughly $13,000 to $20,000 in total taxes (federal, provincial, CPP, EI), depending on your province, resulting in a take-home pay around $50,000-$59,000, with federal tax around 14.5% or 20.5% depending on the portion, plus provincial tax and deductions like CPP and EI.
The bonus is added to your total annual income and taxed according to Canada's progressive tax system, where higher income levels have higher tax rates. Therefore, a big bonus pay may push some of your income into a higher tax bracket and result in a higher effective tax rate on that portion of income.

For example, tax on a $50,000 bonus: Paid to you and your marginal tax rate is 32.5% = $16,250. Paid to you and your marginal tax rate is 37% = $18,500.
One of the most notable differences between bonuses and raises is the duration of the compensation. Bonuses are one-time, short-term financial rewards. A raise is an increase to your current salary for the foreseeable future and provides more long-term benefits.
Percentage method for bonuses
If you receive a bonus separately from your regular paycheck, your employer is probably using the percentage method to calculate how much tax to withhold on your bonus. Here's how that works: The employer withholds 22% of your bonus for taxes if your bonus is under $1 million.
Your bonus was likely taxed at 32% because employers use special IRS rules for "supplemental wages," often applying a higher flat withholding rate (like 22% or sometimes higher if combined with regular pay in the aggregate method) or pushing you into a higher tax bracket temporarily, but you'll get any over-withholding back as a refund at tax time since bonuses are taxed at your actual income tax rate eventually, not a permanent higher one.
